NOVELTY - Preparation of phosphorus hybrid graphene oxide involves mixing graphene oxide with tetrahydrofuran evenly to obtain system A, adding and stirring triethylamine with obtained system A to obtain system B, adding system C containing phosphazene in dropwise to obtained system B to obtain system D, dissolving the silane coupling agent in tetrahydrofuran to obtain system E, adding the water in dropwise to prepared system F at 40-70 degrees C under constant temperature condition of 2-5 hours, and performing washing and drying process through filtration, when the reaction is completed. USE - Preparation of phosphorus hybrid graphene oxide (claimed). ADVANTAGE - Excellent heat stability and flame retardant property of the phosphorus hybrid graphene oxide is ensured. The initial heat decomposing temperature of graphene oxide is decreased to reduce the initial ignition time. The phosphorus content is lower existing material. The phosphorus hybrid graphene oxide is prepared in simple way. The raw material is obtained easily with wide applicability. DETAILED DESCRIPTION - Preparation of phosphorus hybrid graphene oxide involves mixing 1 part of graphene oxide with 500-1000 parts of tetrahydrofuran evenly to obtain system A, adding and stirring 10-50 parts of triethylamine with obtained system A under inert gas protection condition at temperature of 0-4 degrees C under 0.5-2 hours to obtain system B, dissolving the 1-10 parts of phosphazene in 100-400 parts of tetrahydrofuran to obtain system C, adding system C in dropwise to obtained system B at temperature of 0-4 degrees C for 1-5 hours and increasing gradually to 40-70 degrees C under constant temperature condition for 2-5 hours to obtain system D, dissolving the 20-50 parts of silane coupling agent in 200-400 parts of tetrahydrofuran to obtain system E, adding the system E in dropwise to prepared system D at 40-70 degrees C under constant temperature condition of 2-5 hours to obtain system F, adding the 4-10 parts of water in dropwise to prepared system F at 40-70 degrees C under constant temperature condition of 2-5 hours, again under 15-25 degrees C for 10-24 hours, and performing washing and drying process through filtration, when the reaction is completed.
